METHOD OF MAKING CARRIAGE-CURTAIN KNOBS.

SPECIFICATION forming part of Letters Patent No. 788,551, dated. May 2, 1905.

Application filed December 4, 1902.4 Serial No. 133,871.

To all whom, it muy concern,.-

Be it known that I, FRED A. NEIDER, a citizen of the United States of America, and a resident of Augusta, county of Bracken, State of Kentucky, have invented a certain new and useful Method of Making Carriage-Curtain Knobs, of which thefollowing is a specification.

The object of my invention is a Ineans for inserting the shank into and securing the same iirmly to the head of a curtain-knob, which involves few steps and secures the parts rigidly together.

In the accompanying drawings the successive steps of the operation embodying my invention are illustrated.

Figure l is a sectional View of a vise hold- V ing a blank, shown in elevation, above which a swage in the act of descending is shown in section. Fig. 2 is a similar view showing the position and the shape of the blank afterthc swage has descended. Fig. 3 is a sectional view of the blank seated in a block, showing a drill receding' from the same after having drilled a hole therein for the reception of the shank. Fig. i is a similar view showing the means of forcing the metal about the shank to hold the same in the head. Fig. 5 is an elevation of the completed knob.

Referring to the parts, a blank A, formed from a short 4piece of wire, which has had a head a formed thereon in a heading-machine, is inserted between the jaws B B of a vise.

A swage C, having in its contacting face a cavity c', and within the cavity a small projectingpin-point c, is then forced down upon the end of the blank, forming thereon a collar a of a circumference equal to that of head a and a nipple c2, the latter having a small central indentation af. Indentation a3 forms a seat for drill D, which then drills a longitudinal central hole al in the blank, which is then seated in a plate M, having a hole m of the size of the circumference of the collar and head of blank A. Shank E of the carriagecurtain knob is then seated in the hole a", and a plunger F, having a central hole f of a circumference such as to receive the shank E, is then brought down upon the blank. Shank E enters hole f, and the plunger iiattens nipple a2 down around the base of the shank, forcing the metal of the blank firmly about the shank and securing it rigidly in the head of the button.

What I claim is The process of forming a carriage-curtain knob, consisting of forming a blank, having a hole which is to receive the shank and a nipple surrounding the same, inserting the shank and forcing the metal in the nipple down around the base of the shank, substantially as set forth.
